The degree of ionization, formula_1, is defined as formula_2, where formula_3 is the number density of ions and formula_4 is the number density of neutral atoms.

And he thought to himself, They go from one density of medium, the air, into another density of medium, water, without a splash. Look at this picture.

The moon's density is 1.66 g cm3, which indicates that it consists of roughly equal parts water ice and a dense non ice component.

The electron density is related to this by the average charge state formula_5 of the ions through formula_6, where formula_7 is the number density of electrons.
